It's one of those things where you always wonder in the back of your head if it was the right choice. What would it have been like if I had studied writing and literature instead of computer science in school. Very likely, I think I would be writing something similar to this article. It's a tough gig and it's getting tougher by the day.
I can't help but think, though, that I've met a fair number of programmers who find themselves in a similar situation. They get out of a job, go for a while and then just can't seem to get back in. Then what? Do you struggle to make it? Do you cut your losses and try something else? What if that doesn't work? It's a scary thing to contemplate.
